Sitting in California, no dc power. Everything was good, 93% battery, running the microwave to heat up dinner when all dc went dead. No pooched fuses . Anyone that has advice it would be appreciated sitting in the dark
Edited due to my attempt to do math before my first cup of coffee....Either it is dead, or the BMS cut it off for an overdraw?
After going to bed at an unusually early hour we woke up this morning to dc power.! Yes we have Victron where there was no alarm before everything crashed. My guess of the dead battery was wrong. As I mentioned the victron monitor was showing 93% capacity before it crashed. The microwave was only on for a few seconds and just two interior lights were on and the fridge.Agree that your battery is probably dead or hit its discharge limit. Do you hear an audible alarm from the inverter before it died? The discharge limit is set in your battery monitor system. Not sure which one you have, probably Victron.
Have a multimeter on hand by chance to verify battery status?
A classic case where a 10 buck cheapo mulitmeter could likely pin down the problem in minutes.So many solutions depend on having a multimeter, it would be worthwhile to purchase one, any auto supply store will have one. Good videos on uTube for learning how to use it.
That's caught a few folks by surprise.IF you have an inverter, did you check the main fuse box? Often owners don't even know about this. On my 5.0TA, it's hanging from the rear cabinets nearest the main electric cord.

Depending on the exact model of 100 ah hub lion battery you may have either a 100 amp or 150 amp maximum load. The battery BMS will shut off the battery if the load is exceeded. While the 700 watt microwave usually supplied by Escape would be marginal on a 150 amp BMS, the microwave could easily exceed the limits of a 100 amp BMS. After shut down, the BMS will eventually turn the battery back on. It is usually suggested to go with either at least a 200 amp hour battery with a 200 amp BMS or a pair of 100 amp hour batteries, each with a 100 amp BMS in parallel, providing a total of 200 amp output.Thank you to all for your input, we are back on the road with functional DC![]()
700W / 12V = about 59A draw. Even with some inefficiency losses in the inverter and wiring, I wouldn't have thought that a 700W microwave "could easily exceed the limits of a 100 amp BMS".
